Why it matters

Heart disease remains the leading cause of death among women, and many heart attacks and strokes are preventable. This letter highlights an important but often overlooked risk factor - poor oral health - that can significantly impact heart health through the spread of harmful bacteria and inflammation.

The details

Research shows that bacteria from gum disease can enter the bloodstream and travel to the heart, contributing to inflammation that affects the heart and other vital organs. Good oral health habits like brushing twice daily with fluoride toothpaste, flossing, and regular dental check-ups can help prevent this. The letter also emphasizes the importance of a healthy diet, managing blood pressure, taking medications as prescribed, and avoiding smoking and vaping to protect both oral and heart health.
